Hundreds turn out for STEM Career Expo at Fermilab

Between 600 and 700 high school students attended the event, which allows students to meet face to face with career scientists, engineers and mathematicians.

3-D-printed CMS detector

James Wetzel, a staff scientist on CMS at the University of Iowa, used a 3-D printer to make a number of these CMS detector models. The U.S. CMS collaboration is distributing them to U.S. universities that participate in CMS, the Department of Energy, the National Science Foundation and other CMS-related organizations.

Synopsis: IceCube neutrinos pass flavor test

From Physics, April 28, 2015

The IceCube Neutrino Observatory at the South Pole is a large array of photodetectors buried in ice. In 2013, the instrument reported signals from the highest energy neutrinos ever observed. Now, two teams of researchers have independently estimated the type, or flavor, of these neutrinos. As opposed to an earlier analysis, these new results are consistent with the neutrinos coming from cosmically large distances. Further work may begin to probe the physics going on at the neutrino sources.

Sharing the road with pedestrians and bicyclists

Now that the warm weather is finally upon us and bicyclists, joggers and walkers have taken to the roadways, there are increased chances of collisions with motorists.

According to a recent Fermilab Security case report, on March 30, an employee driving to work had a less than friendly verbal exchange with a non-Fermilab bicyclist. The encounter ended with the bicyclist putting his foot on the employee's vehicle and the employee contacting security. On April 8, two employees were walking on Main Ring Road for exercise when they were nearly sideswiped by a vehicle.

We urge everyone to be aware of traffic safety and follow the Illinois Rules of the Road. These rules are enforced at Fermilab, and they apply to motorists, bicyclists and pedestrians alike.

Motorists should watch for pedestrians and bicyclists and respect bicyclists' rights to share the road. Motorists should also remember that driving a little slower for a few minutes beats taking a chance you may regret for life.

Many have voiced concern that some bicyclists ride through stop signs without stopping or looking for oncoming traffic. There have also been complaints that some bicyclists ride more than two abreast, taking up a full lane or more. The Illinois vehicle code (625ILCS 5/11-1505.1) states that "persons riding two abreast shall not impede the normal and reasonable movement of traffic." Although riding two abreast is legal, the Illinois Vehicle Code also recommends riding single-file if possible. This is safer because it presents less chance of bicycles impeding traffic flow. Motorists must leave three feet of space when passing a bicycle. It's the law.

The Fermilab Community Advisory Board has said that bicyclists impeding traffic have been an issue in the Fox Valley area. Batavia and Kane County Forest Preserve police have ticketed bicyclists whose behavior puts others at risk, and Fermilab has issued tickets to bicyclists as well. The penalty for bicycle moving violations is the same as for motor vehicle moving violations.

Safety Update

ESH&Q weekly report, April 28

This week's safety report, compiled by the Fermilab ESH&Q Section, contains one incident.

An employee working in an awkward position felt a pain in his left side where it had been pressed against a cabinet. He received first-aid treatment.

DUGL sees Nepalese earthquake

From Sanford Underground Research Laboratory's Deep Thoughts, April 27, 2015

On Saturday, a devastating earthquake struck
Nepal, one of the poorest
countries on Earth. The 7.8
magnitude temblor, followed
by a 6.7 magnitude aftershock,
destroyed villages and towns,
trapped hundreds on Mt.
Everest, and took the lives of
more than 4,000 people. Many
news sources say that number
is expected to grow as rescuers
reach remote areas.

For about 50 million
years, the Indo-Australian
Plate has been pushing itself
beneath the Eurasian Plate,
a collision that gave rise to
the Himalayan Mountains.
As the plates continue to
collide, pressure builds until
finally an earthquake occurs
to relieve the stress. The
Indo-Australian Plate is pushing under the Eurasian Plate
at a rate of nearly 2 inches
per year.

"This is one of the fastest
convergences on Earth,"
said Victor Tsai, Assistant
Professor of Geophysics at
the California Institute of
Technology. "The collision
is causing the Himalayas to
grow taller every year."
